I hope this doesn't turn into a shitposting thread, because I think you make an interesting point
The world, and history, is full of situations where people said "Nobody will ever be able to top this." Records which were thought unbeatable, beaten. In sports, video games, speed-running, all over the place.
And so it might be motivational for some up and comers (and maybe the less cynical veterans) to remember that. In 2007/08, folks that were Quake/TFC veterans or whatever may have possibly thought "We are the pinnacle, we are the best. We've put in tons of work, and folks will never top what we do" etc, and that seems funny to look back at now.
I think we do understand the various skill ceilings a lot better these days, especially after 10 years, and we've picked through the game code about as thoroughly as possible, but never say never - in a few more years, we may find it funny to look back and see that one player dominated the NA scene for 3-4 years in a row.
